Recieved the 525 sprockets. I ordered the 15/46 combination originally, but settled for 16/46 as 15 was out of stock when I contacted them back?
I wish they'd told me from the begining.
Was advised the 47 wouldn't fit the chain I'd purchased with the 16, so settled for 16/46.
......Only to find, after abit of grease and sweat, the chain still too short on 46.. Doh.


So I went to my local Yam blokey and got another chain, couldn't be bothered to hasstle OTR again. It seemed rude of me, postage time too.
Whilst sorting chain at shop had a word about 525 sprockets, Blokey said sourcing them shouldn't be a problem as they can get all sorts. They use a company for custom made sprockets, but he doubts our bike has a rare stud pattern/spacing. I'll jot down the numbers on the 525's and next time I'm in the shop have another chat.
